FINDLAY, Ohio, June 3, 2019 – MPLX LP (NYSE: MPLX), WhiteWater Midstream (WhiteWater) backed by First Infrastructure Capital, and a joint venture between Stonepeak Infrastructure Partners (Stonepeak) andWest Texas Gas, Inc. (WTG) have reached a final investment decision to move forward with the design and construction of the Whistler Pipeline after having secured sufficient firm transportation agreements with shippers. The majority of available capacity on the planned pipeline has been subscribed and committed by long-term transportation agreements. WhiteWater and MPLX expect that the remaining capacity will be fully subscribed in coming months.

The Whistler Pipeline is being designed to transport approximately 2 billion cubic feet per day (Bcf/d) of natural gas through approximately 475 miles of 42-inch pipeline from Waha, Texas, to the Agua Dulce area in South Texas. Supply for the Whistler Pipeline would be sourced from multiple upstream connections in the Permian Basin, including direct connections to plants in the Midland Basin through an approximately 50 mile, 30-inch pipeline lateral, as well as a direct connection to the 1.4 Bcf/d Agua Blanca Pipeline, a joint venture between WhiteWater, MPLX and Targa. Agua Blanca Pipeline crosses through the heart of the Delaware Basin, including portions of Culberson, Loving, Pecos, Reeves, Winkler and Ward counties.

“The decision to move forward with this project after securing sufficient commitments from shippers demonstrates our disciplined approach to investing,” said Gary R. Heminger, MPLX chairman and chief executive officer. “Whistler is expected to provide reliable residue gas transportation out of the Permian Basin, which is vital to our growing gas processing position and producers in the region.”

“The WhiteWater team is excited to partner with MPLX and develop incremental transportation out of the Permian Basin, as production continues to dramatically outperform consensus estimates,” added Christer Rundlof, CEO of WhiteWater. “Whistler will tie directly into the most attractive markets in South Texas, including the growing LNG and Mexican markets.”

The Whistler Pipeline is expected to be in Service in the third quarter of 2021, pending the receipt of customary regulatory and other approvals.
